CAN FORMING AND SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 395,788, dated January 8, 1889.

Application filed September ll, 1888. Serial No. 285,105. (No model.)

To all whom t may concern:

Be it known that we, FRANK I\[.LEAV1TT,'a citizen ot' the United States, residingin Brooklyn, in the coui'ity ot' Kings and State of New York, and EDWIN NORTON, a citizen of the United States, residing' at ililaywood, in the county oi' (look and State of Illinois, have invented a new and useful Improvement in Can-Body-Forniing and Side-SeamSoldering io Machines, of which the following is a speciiication.

Our invention ifi-)lates to combined can body-forming` and side-seam-soldering ma chinos.

The object ot' our invention is to provide a machine which will operate to form the canbody and solder the side seam at one continuous operation, to the end that the cairbody may always have Aits side seams in proper po- 2o sition to the soldering devices while being conveyed to or through the same, and thus secure more perfect work than can be attained where the proper positioning ot the can-body in the soldering device depends upon hand labor. Another result secured` by our invention is the saving of time, labor, and expense, as the cans can be manufactured more rapidly and cheaply.

In practicing` our invention any well-known 3o type or kind of body-forming machine may be combined with any suitable or well-known form of side-seam-soldering machine. IVe prefer, however, to use the kind of can--bodyforming machine which is shown and de- 3 5 scribed in Patent No.`250,266, granted to said F. M. Leavitt, November 29, 1881, and the kind of sideseam-soldering machine which is shown and described in Patent No. 250,096, granted to said E. Norton, November 29,1881.

4o The invention consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specilication, and in which similar letters of reference indicate like parts. Figure 1 is a front elevation of a machine embodying our invention. Fig. 2 is a rear elevation of the body-former portion of the machine. Fig. Si is a partial vertical longi- 5o tudinal section on line f3 3 ot Fig. 1. Fig. t is a horizontal section on line fl et ot' Fig. 1. Fig. is a detail vertical sectional viewrshowing the movable guides. Fig. t3 is an enlarged detail view oi' parts hereinafter to be described. 5 5 Fig. 7 is a side elevation of the machine. 8 is a partial cross-section on line S 8 of Fig. 3. Fig. El a detail view showing the edge-folding devices. Fig. 10 is a detail view of the blankeed slide.

In said drawings, A represents the frame; B, the horn around which the flat sheet out ot' which the can-body is termed is folded or bont.

O is the table upon `which the -tlat sheetmetal blanks X are placed preparatory to being `fed into the machine bythe reciprocating feed-slide D.

E E and E E are the guides which support and guide the sheet as it is advanced by 7o the feedslide D, rst to the vertically and horizontally reciprocating edge-folding devices F F F2, and then from said folders into position over the horn In. The guides E E serve to support the sheet, and they or their supports have vertical 'fianges or parts c e for the edges of the sheet to abut against, in order to keep the sheet true and square with the edge-foldingdevices F F F2 and with the horn B. The horn B is secured to the frame 8o of the machine below the level of the feedguides E E', so that the feed-sllide D will deliver the sheet above and on top ot the horn B.

The edges of the sheet X, which are interlocked upon the side seam of the cairbody, are folded one up and the other down by the edge-folding devices F F F2, to form hooks as indicated in Fig. 9, and capable of being interlocked, as indicated in Fig. 8, when the sheet is wrapped around the horn. 9o

Vhen the blank X is fed or advanced over the horn B, its middle portion is supported by the horn B, while its edges are supported by the guides E E. These guides E E are made movable, so that they may be withdrawn out of the way to permit t-he sheet to be bent or folded downward around the horn B. To insure the retention of the sheet in a horizontal plane, so that the vertical guide- Iiangese on. the supports for the guides E will properly center the dat blank over the horn B, we provide a middle guide-bar, E2, between which and the horn B the sheet. X is fed. The front end of this guide is slightly turned up, as indicated at e so that the sheet may readily enter beneath the same. The space between the guide El and the horn` B should equal or but very slightly exceed the i thickness of the sheet X.

The sheetX is folded downward around the horn B bythe vertically-reciprocat i ng semici rcular-shaped bending device (i, and the horizontallyreciprocating bending devices G G', which also serve to interlock the hooked edges ai :i: of the sheet, as indicated in Fig. S. The folding device G is furnished with a longitudinal groove, g, to receive the central upper guide, E2, as indicated in Fig. S, so that said guide will not interfere with the proper bearing of the folder G against the surface of the sheet as it is folded around the horn. under surface of the guide E? preferably conforms to the circle of the horn or the folder G, and it is preferably mounted on sprin g8,

vwith guide-pins g", so that it will hold the sheet under the pressure of the springs terlocked or passed by each otherbythehoril zontally-reciprocating folders G G', and then again expanded to the fullv interior diameter of the can to properly interlock` or pull the hooks against each. other prelmratory to the seam closing or squeezing operation.

H is the device for closing or squeezing-the interlocked hooks .1: lirmly together. This seam-closing device operates in cmijunction with the lower surface of the horn B, closin the interlo-cked folds of the side seam against said horn. This closing `device preferably consists ot' a reciprocating plunger or bar, ll', adapted to be moved up against the horn. It however may be made of any other suitable construction known. to the art-as, for example, a revolving roller.

The horn B or ,its segments B is furnished with longitudinal grooves Al), for the spring ngers or pawls 7l: of the reciprocating canbody extractor or conveyor device K to lit in. The can-body, al'ter being formed around the horn B, is extracted therefrom and delivered into the carrier device L of the soldering-machine by the reciprocating extractor or conveyer K.

The blank X is delivered centrally over the horn B and folded downward around it, so that whenl the hooks ,13 .r of the sheet are interlocked and the side seam, formed,

The

such seam will bc at the lowcrmost point ot' the can, or diametrically uilderneath its axis.

The extractor device K operates to remove the can-body from the horn and deliver itinto the carrier L of the soldering-machine without giving the can-body any axial rotation, so that the can-bodies will always have their side seams accurately and positively turned into proper position for soldering as they are conveyedovcr the soldering bath or device )l and the aeiding or flnxing device N by the carrier L.

'lhe can-conveyer or extractor device K reciprocates on a suitable guide-way, K', on the frame of the machine. The hook -shaped spring fin or pawls 7a operate to hook over the rear end of the can-body on the horn B and pull the can-body off the horn onto the track or guide K2, which supports the canbody as it advanced into the soldering device of the machine. The track K2 is furn ished with inclined projections 7c', over which the can-body :r2 rides as the extractor-slide K advances, and which serves to prevent the spring-iin gers L 7: from pushing the can-body backward on the return movement. The holdiiig-projections 7U" are inclined or camshaped toward the horn and abrupt at their other end, as indicated clearly vin Fig; 3, so that the can-bodies may ride over them in one direction, but not in the other.

The conveyer K operates simultaneously upon two can-bodies, being' provided with a second pair of pawls, fingers, or projections, r?, which serve to advance or convey the can-body which has been delivered by the extractoriingcrs K from the horn B onto the guides K2, into position 1o be caught and advanced bythe carrier L of the solderingmachine. The fingers /r move the can-body from the horn B into position beyond the projections r. on the track K2, to be caught by the fingers or pawls k2. The pawlsor iingers 75 are preferably normally pressed outward byslnlings. (Notshown.) lfnosprings, however, are empl oycd, th e can-body will yield or spring sul'iiciently, because it is removed from the horn when these lingers lr? pass back of it.

The carrier device L of the soliflering-machine preferably consists of a link chain mounted upon sprocket wheels or pulleys L', the openings in the links being large enough to receive the can-body within the same. As the links of this chain have, preferably, no devices for supporting the can-body, the canbody rides upon a guide-track, L2, as it advanced by the carrier. The carrier-chain Lis guided or supported by a track or way, L3, upon which it rides. The track LQ-is, in fact,but an extension of the track orgnide K2, along which the can-bodies are carried by the conveyer device K. The track L2 is provided with suitable depressions, L4, to permit the seam of the can-body to pass through or come in contact with the acid or .flux in the bath N and the solder in the solder bath M. `An upper guide,

TOO

IIO

L, serves to guide the can as it passes through the solder bath and insure its proper immersion therein,

L*j is a wiper device for wiping the surplus solder from the outside of the seam as the canbody passes under the hood or guide L7.

L3 L8 are heating devices for heating the solder and. the acid or linx baths. 'lhese heaters are preferably gas-jets.

The pulleys L L are preferably six-sided. The pulley L, which is adjacent to the canbody-:forming devices, is mounted above the can-body tracks K2 L2, about as indicated in liig. il, so that the can-body-conveyer device K may carry the can into or under the link of the chain while said link .in an inclined position, and so that the rear end or crossbar of the link as it advances and descends toward the can-body tracks K2 L2 will catch or strike against the rear end ot' the can-body and thus push it along. 'lhe reciproca-tingl feed-slide K thus operates to push the canbody within the opening of the link of the chain while the llink is in an inclined position.

The feed-slide l) operates simnltanemisly upon two successive sheets, serving to adl vance one sheet from the edge-folders I? l1" F2 into position above the horn l, while the lnext succeeding` sheet is advanced from the table C to the edge-folders F F lf2. rlhe feed-slide l) is provided with inclined projections or pawls d and d. These pawls or projections are adapted to reciprocate under the sheet X, which lies upon the guides E or table C, when the feed-slide makes its backward movement, but catch the sheet andv push it forward as the feed-slide makes its forward movement. As the slide l) makes its backward movement, the sheet is supported and held by the guides. At this time also the forward sheet, which is over the horn, is also held and clamped by and between the horn and the movable springactuated central guide or clamp, E2, as hereinbefore described.

P is the main illriving-shaft of the machine. From this shaft motion is communicated to the counter-shaft P and the (.am-shafts P2 P2 by suitable gears, p p, and to the lower counter-shaft, P, by beveled gears p2 and vertical coimeeting-shaft p. The feed-slide l) is reciprocated by a slotted lever, D', connecting-link d2, lever d, and link d", the slotted lever D being operated from the shaft Pi", through a crank or wrist pin, (l5, which is furnished with a slide, d, that reciprocates in the slot (ZT in the lever 1). 'lhe extractorslide K, which operates to convey the canbodies from the horn B to the carrier L, is rcciprocated by this same lever D through similar connecting mechanism-via link 7c3, lever 7u", and link Ici.

The vertically-reciprocating edge-folders lF F-one on each side-are reciprocated in opposite directions from the cam-shafts P2 P2 by suitable levers,f, connecting-linksj" j", and

`are all well known to those skilled in the art, i, and are fully shown and described in said cams fgf?. The horizontally-ieciprocating edge-folders l?" F are moved by levers ff and cams]LALL f4. The lower folder, F2, is stationary and constitutes, `in fact, the continuation of the guide E. 'lhis lower steel folderblade, F2, is bolted or otherwise rigidly secured to the guide E, as shown in Fig. 9. The upper folder, lf2, is secured to a verticallymovable lever, f, pivotally connectei'l by a link, f6, to the frame at f", so that the folder F2 may be given an up-and-down and also a lateral movement to release or loosen the sheet X from the folders after the hooks a; are formed thereon. This folder F2, or its sliding lever f5, is operati-id by a cam, fs, through the link fi and slide fw. The upper folder, F2, bein thus movable, serves to clamp the sheet during the foldingI operation between itself and the guide E. To similarly clamp the sheet near the opposite edge, a clamp, F3, operates in conjunction with the lower stationary folder, F2. 'lhe clamp F3 is operated by a cam, fu, and connecting-link -112 The folder device (i, which operates io bend or partially bend the sheet around the horn, is operated b v a cam, G2, on the shaft P', the slide G3, upon which the folder is G mounted, being furnished with friction-rollers G, that impinge against the cam. G are the guides in which thc slide G reciprocai'es. The horizontally-movable folders Gr G are reciprocaied in their `guideways g2 by cams g on the shaft P, connecting-links g4, levers g, and links g,

The horizontally-movable guide-plates E 5 are witinlrawn by springs e2, Fig. 5, during the movement ofthe folding device G; and these guide-plates are held out in position for supporting the edges of the sheet, when ther folder (l is in its upper position, by a bent lever, e3, which is connected tothe slide G3 by a slotted pin, c, secured to a bracket, e5, on said slide Gi'. When the slide G3 begins to descend to cause the folder G to bend the sheet X down and around the horn B, the springs e2 will at once withdraw the guides E', and thus permit the sheet To be bent downward.

'lhe wedge lby which the horn lf3 is contracted and expanded, is operated b v a lever, B3, from a cam, l", on the shaft P3.

The seam closing or squeezing' device H is reciprocated or operated ,by a cani, 7i, on the shaft P3. The slideH, to which the seamcloser H is secured, is provided with a frictionroller, h', to bear against the cani 7i.

The construction of the horn B, and of the mechanism for operating its expanding and contracting parts, of 4the table C, of the feedslide l) and the mechanism for operating it, of the hook or edge folders F F F2 and the mechanism for operating the same, and of the body forming or bending devices G G,

need not, therefore, be here described more in detail.

The movable can-body carrier L is operated from the main driving-shaft l by suitable connecting-shafts and mechanism, R lt R2, communicating with the sprocket wheel or pulley L at the farther end of the machine. This connecting mechanism is made to drive the farther pulley L', in order 'that the lower line of the chain L, which carries the canbodies, may be pulled, instead of pushed, as would, to a greater or less extent, be the case if the power were communicated to the pulley L adjacent to the can-body-forming device.

The construction of the carrier L, the tracks L2 and L3, the wiper device, and the other parts of the soldering portion of the machine are :fully shown and described in said Patent No. 250,09li, and need not therefore be here l set forth in detail.

As the sheet X is fed in above the horn l and folded downward around it, the tendency of the sheet to bend or lop down at its ends or edges acts in the direction the sheet moves during the folding movement, and to aid or assist the folding' of the sheet, instead f to oppose the same, as heretofore has been the casewhere the sheet has been Afed in below the horn and folded upward around it.
